PHOTOGRAPHIC-PRINTING FRAME.

SPECIFICATION forming part of Letters Patent No. 775,101, dated November1 5, 1904.

' Application filed December 28, 1903. Serial No. 186,774. (No model.)

To [LZZ whmn it may concern:

Be it known that 1, WILLIAM E. DoBBINs. a citizen of the United States,residing at Ashbourne, county'of Montgomery, State of Pennsylvania, haveinvented a new and useful Improvement in Photographic-Printing Frames,of which the following specification.

My invention relates to photographic-printing frames.

It consists of means for enabling prints to be taken of portions of afilm without cutting the same.

Itfurther consists of other novel features of construction, all as willbe hereinafter fully set forth.

Figure 1 represents a top plan view of a photographic frame embodying myinvention. Fig. 2 represents asection through the line 00 00, Fig. 1.Fig. 3 represents an end view of the device shown in Fig. 1. Fig. 4 is afragmentary top plan view showing a modification of my advice.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a printing-frame provided withthe usual back 2 and clamping devices 3. Through the ends of the frameare cut slots 4 4. Secured to the ends of the frame are C-shaped springs5, on the inner ends of which are lugs 6. Sprung between the lugs 6 6 atone end of the frame 1 is aspool 7, containinga film 8. At the free endof the film 8 is attached a tag or label 9, the end of which is slippedinto a slot 10 in the spindle of a second spool 11 at the other end ofthe frame 1. after developing is rewound upon the spool 7 which isengaged between thelugs 6, as shown,

and passed through the slot 4 and over the.

glass 12. The end of the label-tag 9 is then engaged in the slot 10 ofthe second spool 11, and the film is wound off the spool 7 onto thespool 11 step by step as the pictures are successively printedtherefrom.

In the form of the device shown in Fig. 4

shown and described.

It is clear that the film the brackets or springs 5 and bearing-lugs 6are shown as forming part of the plate 13, which serves besides tostrengthen the frame 1.

It is evident that various changes may be made by those skilled in theart which will come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein Thus instead of the slots 4 shown it is clear thatthe ends of the frame may be cut away, so as to permit the strip or filmor other negative to pass directly over the glass.

The particular advantage of my invention lies in the fact that byunreeling the film directly from the spool without cutting it to piecesit is unnecessary to soak it in glycerin or take anyother means toprevent its curling. Inthecase of continuous picture-films it is ofgreat advantage.

By means of the spring connection,.which formsthe essence of myinvention, the spools may be readily connected with or detached from aframe, while at the same time they are held by the resilience of thesprings with sufiicient friction to prevent their turning except by thehand of the operator.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A printing-frame the ends of which are slotted to pass a strip offilm, and a pair of spring-lugs secured at each end of said frame andadapted to detachably and resiliently engage a film-holding spool.

2. A printing-frame the ends of which are slotted to pass a strip offilm, U-shaped springbrackets at the ends of said frame and lugs at thefree ends of said brackets adapted to detachably and resiliently engagein recesses in the ends of a film-holding spool.
